Title: Improvements in or relating to guns for driving dowels
IPC: B25C1/12
Filed: 1961-04-05
Abstract: 985,986. Cartridge-operated fastener driving tools. J.M. F. MASSACRIER. April 5, 1961 [Jan. 19, 1961], No. 12203/61. Heading B4C. A cartridge-operated fastener driving tool has a rotatable magazine cylinder 2 with parallel cartridge chambers 2<SP>2</SP> each of which is locked successively in alignment with a barrel 3 removably mounted in a body sleeve 1<SP>3</SP> by means of a sliding ring 20 and a barrel shoulder 3<SP>2</SP> which limits the rearward movement of the barrel. Springs 19 are interposed between the ring 20 and shoulder 3<SP>2</SP> and between the ring 20 and a mouthpiece 18 mounted at the end of a cocking slider 9 which on being pushed rearwardly cocks the firing mechanism in the manner described in Specification 844,222, disconnection of the mouthpiece by loosening a screw 21 permitting removal of the barrel 3. The cylinder 2 rotates on a removable spindle 5 which, after the cylinder 2 has been removed from the body 1, can be used to operate on an extracting sleeve 7 to eject the cartridges as described in Specification 844,222. The shield 4 is secured in position by a spring-urged rod 24, Fig. 3, formed with a laterally projecting head 24<SP>1</SP> which in the position shown prevents removal of the shield, but which can be turned angularly through 180 degrees to allow its removal. In the position Fig. 5 (not shown) the head 24<SP>1</SP> lies in the path of the mouthpiece 18 and prevents a sufficient rearward movement of the slider 9 to cock the firing mechanism. In the secured position of the shield, angular movement thereof can be effected. A further safety device comprises a lever 28 pivoted at 28<SP>1</SP> to the cocking slider 9 and spring-urged so that one end 28<SP>2</SP> engages in a notch in the body and prevents movement of the slider 9. Depression of the lever to permit such movement is only possible if the shield 4 is in position when it moves a spring-urged plunger 30 so that a stud 30<SP>1</SP> secured thereto can engage in an aperture 28<SP>3</SP> in the lever arm. A narrow gap is provided between the front surface of the cylinder 2 and the body of the tool and a rear bearing portion 3<SP>1</SP> of the barrel extends into the gap. The tool is provided selectively with a plurality of barrels and co-operating cylinders corresponding to different gauges of fasteners and having different lengths, the sums of the lengths of the barrel and cylinder corresponding to different gauges being the same. Reference has been directed by the Comptroller to Specification 844,222.

Patent GB-942109-A (GB)
Title: Improvements in or relating to milk-based foods
IPC: A23G9/40
Filed: 1962-03-30
Abstract: A food composition contains milk solids and comprises a ternary gel of milk proteins, sugar and water, in which the amount by weight of water does not exceed 72%, and the ratio by weight of non-milk sugar (expressed as sucrose) to the non-fat milk solids is in the range 0.24 to 1, preferably 0.39 to 0.7.  Compositions containing 19-34% non-fat milk solids 8-19% non-milk sugars, and in which the sugar and milk solids together comprise 32-48% are preferred.  The composition is produced by mixing together milk solids, sugar and water, and heating the mixture in an airtight container and without any local overheating occurring, to produce gelification of the milk proteins with the sugar and the water. The heating may be conducted at temperatures within the range 90 DEG  to 110 DEG  C. for periods of from 5 minutes to 4 hours depending on the desired consistency.  Ice compositions are obtained by cooling a composition having the consistency of a custard to a temperature equal or lower than its freezing point, even down to -22 DEG  F. without any trituration. Powders containing 2 to 20% of water may be obtained by dessicating creams or custards.  When whole or skimmed natural milk are employed, the mixture is first concentrated until it contains not more than 72% by weight of water, before heating in the specified manner.  Milk: natural milk, evaporated milk, partially or wholly skimmed milk, and powdered milk.  Sugars: sucrose, glucose, fructose, maltose and lactose.  Flavouring or colouring agents: essences such as those of lemon, orange, aniseed, coffee and vanilla, fruit juices, jellies or preserves chocolate, aromatic powders such as cinnamon, angelica, cocoa and praline extracts, caramel concentrates and edible colouring agents.  Optional thickening agents for producing special forms e.g. a mousse: pectin dextrin, starch, flour, gelatine and gums. Stabilizers such as salicylic, benzoic or sorbic acids or their soluble salts and also methylene pyrocarbonate may be used when lawful.  It is stated that methylene pyrocarbonate may be added to the mixture before heating it; the compound disappears in a few hours by decomposition into water and carbon dioxide.  Examples are directed to the preparation of vanilla, coffee and caramel flavoured custards, creams and ices.

Title: Improvements in or relating to automatic firearms
IPC: F41A5/00
Filed: 1944-06-29
Abstract: 598,051. Smallarms..JOHNSON, M. M. June 29, 1944, No. 12378. Convention date, May 13, 1943. [Class 119] In an automatic fire-arm comprising lugs 3, 4, Figs. 8 and 9, on each side of the front of the bolt, which transmit the breech pressure to lugs on the receiver, the abutting surfaces of the lugs are inclined so that the breech pressure transmitted to the bolt by a slide S, Fig. 7, moved by gas pressure and a spring, tends to produce rotation of the bolt and thus unlocks the lugs. Also the slide S has a surface 9 which engages the top of the lug 4 and prevents rotation and unlocking until the slide has moved a predetermined distance. The main feature of the invention is an inclined cam surface 11 on the slide S which cams the bolt into locked position and a cam surface 12 which cams it into unlocked position. To counteract the thrust between the surface 9 and the lug 4, the receiver is provided with a flange 14 overlying the slide which also has a depending part 16 preventing outward movement of the slide.

Title: Parking installation for motor vehicles
IPC: E04H6/24
Filed: 1961-04-06
Abstract: 951,958. Mechanical garages; garage lifts. A. T. DE SAINT-ANDRE. April 6, 1961 [April 6, 1960], No. 12456/61. Headings B8E and B8H. [Also in Division B7] Motor vehicles are transported from an entrance 5 of a multi-storey garage to parking bays 4 in an enclosure situated above or below the entrance level by a track 2 which is horizontally movable, as on rails 7, along a central passageway 12 between two rows of parking bays. The truck has a vertically movable platform 3 which in turn carries laterally extensible arms 17. In use the arms are extended to pick up a vehicle, the truck is then moved bodily with the arms retracted to bring the vehicle opposite a required parking bay and finally the platform is raised or lowered and the arms again extended to deposit the vehicle. In Figs. 1 and 2 the parking bays are all on one below-ground level and the truck runs on underground rails: in Fig. 15 (not shown) there are two above-ground parking storeys and the truck runs on rails at the entrance level. In both forms the platform is raised and lowered by winches 11, Fig. 2, and cables 10 which are trained each over a single fixed pulley 9 and connected to the platform either directly, as shown, or as in Fig. 3 (not shown) by way of a pair of further pulleys at the top and bottom of a vertically movable mast at each side of the platform. The arms 17, when extended, move in channels 18 in the floor below the vehicle at the entrance or parking bay and comprise outer channel members 21, Figs. 4 and 5, extensible with respect to intermediate channel members 20 themselves similarly extensible over rails 19 fixed to the platform 3. The extension is effected by the drive over pulleys 31 of two cables 26 which interconnect lugs 27 and 28 on the rail 19 with lugs 30, 29 respectively on a channel member 21, and by like driving of channel member 20 through cables 32. The outer channel member may have support wheels 42, Fig. 7, running on the base of the channel 18 in the floor below the vehicle, these wheels being carried by bell cranks 40 whose free ends replace the lugs 29, 30 of Fig. 5 and which are operated to raise the platform as it moves into position below the vehicle thereby lifting the latter from the floor. The extensible arms may (see Fig. 9) be made movable longitudinally of the truck 2 by being each mounted on supports 53 driven by the screws 58 to move inwardly in pairs so that their outer channel members 50 act as illustrated to lift the vehicle wheels. The extensible arms may be mounted on a turntable (see Division B7) rotatable about a vertical axis with respect to the platform. In such case, the turntable drive may incorporate devices (Figs. 13 and 14, not shown) in the form of linkages so arranged that between successive dead centre positions thereof the predetermined rotation (e.g. 90 degrees or 180 degrees) of the turntable takes place. These devices control the accurate setting of the relative orientation of the extensible arms in accordance with that of the entrance, exit and parking bays.

Filed: 1946-04-26
Abstract: 611,431. Extracting juice from citrous fruits. DEHN, S. G. (Sunbeam Corporation). April 26, 1946, No. 12666. [Class 28(ii)] A fruit juice extractor of the type having a vertical rotating reamer surrounded by a juice bowl, has a perforated strainer plate which is oscillated by an eccentric mounted on the reamer drive shaft. The strainer plate 24, Fig. 1, is supported at its rim by an annular ledge 25 formed in the lower part of the juice bowl 11. The upwardly domed centre hub 31 of the plate 24 houses a cam follower plate 29, preferably made of a graphite-impregnated, laminated plastic, which engages an eccentric 28 mounted on the reamer shaft 18 so that rotation of the shaft causes the strainer plate to oscillate about a fulcrum formed by a key 26 in the bowl, and a corresponding notch 27 in the plate. In a modification, Fig. 3 (not shown), the domed centre hub directly engages an eccentric inner face formed within the reamer. In a further modification, Fig. 8 (not shown), a second fulcrum is arranged diametrically opposite the one shown at 26 in Fig. 2 so as to limit the movement of the strainer to a straight line. The cam follower plate is also modified to have a square hole coacting with the eccentric. In a further modification, Fig. 6, the fulcrum 26 of Fig. 2 is replaced by forming the centre stub portion of the base of the bowl with rib portions over 43 which co-operate with socket portions 42 formed in the centre hub of the strainer to form a series of fulcrums.
